Add /compact skill for manual context compaction (#817)
* feat: add /compact skill for manual context compaction
added /compact session command to fight context rot in long-running sessions. Uses Claude Agent SDK's built-in /compact command with auth gating (main-group or is_from_me only).
* simplify: remove group-queue modification, streamline denied path confirmed against fresh-clone merge.
* refactor: extract handleSessionCommand from index.ts into session-commands.ts
Verified: 345/345 tests pass on fresh-clone merge.
